On February 24, 2022, three-year-old Omnishence Buchanan was shot and killed by her biological father, Marcus Buchanan, 36, inside their home at 306 Kathy Lane in Granbury, Texas (Hood County). Marcus also shot and killed his wife Rita Buchanan, 34 (Omnishence's mother), and Rita's 13-year-old daughter from a prior relationship, Julia Flores, before fatally shooting himself in an apparent murder-suicide. Officers discovered all four deceased during a welfare check shortly after 2:45 p.m. The family had moved to Granbury from Las Vegas approximately six months prior, and neighbors reported no visible signs of distress beforehand. Marcus had no criminal record. The perpetrator was never formally charged as he died at the scene.

Notable Details
The NY Post article provides notable context that the Buchanan family had recently relocated from Las Vegas approximately six months before the incident, and that neighbors reported seeing no signs of distress prior to the killings. The NY Post also notes: "Child welfare officials, meanwhile, declined to indicate if they had a prior history with the family." Additionally, the TCFV report confirms that Rita is survived by "her two sons," indicating there were other children in the family who were not present or not harmed during the incident. These details — the recent relocation, absence of observable warning signs, and the existence of surviving children — are contextually relevant to understanding this case.
